FUNCTIONAL DESCRIPTION
The 1515-series device is a fixed, single-input, single-output, passive delay
line. The signal input (IN) is reproduced at the output (OUT), shifted by a
time (T
D
) given by the device dash number. The characteristic impedance
of the line is given by the letter code that follows the dash number (See
Table). The rise time (T
R
) of the line is 10% of T
D
, and the 3dB bandwidth is given by 3.5 / T
D
.
